45281: He caused some harm to his friends; does he have to tell them if he intends to repent?

I got to know one of the youth who have gone astray, and he used me to make some young people fall into his trap. I helped him in fact, but some of that did not happen, praise be to Allaah. I even helped him to do witchcraft against one young man, but it did not harm him, praise be to Allaah.
I have repented now, and I keep away from that deviant young man and keep company with good people. I have also started to memorize the Holy Qur’aan.
My question is: is it one of the conditions of my repentance that I should tell him about the witchcraft I did, in order for my repentance to be accepted?.

Praise be to Allaah.

We praise Allaah for guiding you to repent, and to keep away
from these bad friends. You have to keep on thanking Allaah and asking Him
to make you steadfast and to guide you.

The rights of other people must be restored if the wrong done
involved material things. With regard to intangible things, such as gossip,
the correct view – and Allaah knows best – is that he does not have to tell
him if the person does not know about that, so it is sufficient to pray for
forgiveness for his sin, and to pray for forgiveness for his brother too, in
return for the harm done by his gossiping and backbiting about him.

The harm done to this young man by means of plotting and
witchcraft comes under the heading of intangible matters, so you do not have
to tell him about what you did; it is sufficient for you to fulfil the
conditions of sincere repentance, namely regretting what you did, giving it
up, and resolving not to go back to it again, as well as stopping the
evildoer and others as much as you can.

But if that young man or anyone else knows about the plots
and tricks you used against him, then you have to apologize to him and ask
for his forgiveness, because you are only allowed not to tell him if he did
not know so that he will not be upset by that, and lest that lead to cutting
off ties and the stirring up of enmity and hatred between you. But if he
knows that you did this evil thing, then the reason not to tell him is no
longer applicable and your apologizing to him will serve a purpose.
